Question

a) (+ 15) : (+ 3) =
b) (+ 20) : ( – 4 ) =
c) ( – 35 ) : ( + 7 ) =
d) ( – 40 ) : ( – 5) =
e) ( – 77 ) : ( + 11 ) =
f) 500 : (– 25) =
​

Answer 1

Oie, Td Bom?!

A)

$( + 15) \div ( + 3) = 15 \div 3 = 5$

B)

$( + 20) \div ( - 4) = 20 \div ( - 4) = - (20 \div 4) = - 5$

C)

$( - 35) \div ( + 7) = ( - 35) \div 7 = - (35 \div 7) = - 5$

D)

$( - 40) \div ( - 5) = 40 \div 5 = 8$

E)

$( - 77) \div ( + 11) = ( - 77) \div 11 = - (77 \div 11) = - 7$

F)

$500 \div ( - 25) = - (500 \div 25) - 20$
